clear() is used to remove all the elements. This method does not require any arguments.
It is not identical to the usage of the INITIALIZE TO NULL statement, because the statement removes only the values leaving the array elements intact.
Syntax:
ar.Clear()
Usage example:
clear() can also be used with multi-dimensional dynamic arrays:
DEFINE ar DYNAMIC ARRAY OF CHAR(15) ... FOR i = 1 TO 5 #the array has 5 elements LET ar[i]="element "||i END FOR CALL ar.clear() #the array has no elements
